The MODIS Characterization Support Team (MCST) is dedicated to the production of a high quality MODIS calibration product. MCST developed the L1B algorithm and all parameters necessary to run the code, and develops the quality assurance and verification of L1B product enhancements. The MCST flight operations team supports MODIS operations on orbit through command and control of the instrument. Responsibilities include developing MODIS operations scenarios, creating the operations database, monitoring instrument health and safety, and operating the MODIS on-orbit.
The purpose of the MODIS Instrument Operations Team (IOT) is to plan, schedule, and monitor MODIS activities. The MODIS Instrument Operations Team schedules a daily set of Operational Activities using the Instrument Support Toolkit (IST) software package provided by the EOS Flight Operations Segment.
MCST is dedicated to the production of a high quality MODIS calibration product. This product is a precursor to every geophysical science product. MCST works for the Science Team Leader and is responsible for developing and maintaining the calibration product (L1B algorithm).
SFE Anomaly: After passage through the SAA on 2014/299 ~01:35 EDOS observed corrupted MODIS data. The cause was traced to a formatter card that had become out of sync resulting in the corrupt data. Only MODIS data is processed by this card so no other instruments were affected. FOT successfully reset the card and returned data flow to nominal operation. Expect a data loss from 2014/299 01:35:00 – 18:47:00. Exact loss time still to be confirmed by FOT.
Terra MODIS Collection 6 Level 1B products will be reprocessed to correct for the long term drift observed in the reflectance trending of band 5. More details regarding the reprocessing schedule can be found here: http://ladsweb.nascom.nasa.gov/news/news080414.html
Terra experienced an anomaly for B36/D7 beginning on 2014109.1405. Unlike previous instances of this unknown electronics/formatter anomaly, the detector behavior has not returned to normal.After 2 weeks continually being in the anomaly state, the decision was made to change the QA flag for this detector from 'Noisy' to 'Inoperable'. All Band 36 detectors are currently flagged as Noisy.
This QA change will be in effect from the LUT versions 18.104.22.168 (Collection 5) and 22.214.171.124 (Collection 6)
May 4, 2014 marked the 12 year anniversary of Aqua launch. The MODIS instrument on-board the Aqua spacecraft has well surpassed its design lifetime, but continues to provide valuable datasets for studies of Earth's land, ocean and atmosphere systems.
MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications).
These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.
MODIS was launched on the EOS Aqua spacecraft on Saturday, May 4, 2002 at 09:55 GMT. MODIS Aqua "First Light" was achieved when the MODIS Nadir Aperture Door opened on June 24, 2002 at 23:22:48 GMT. The Aqua MODIS instrument began taking data using side-B electronics. For a complete look at the EOS-PM/ Aqua mission, see http://aqua.nasa.gov/.
MODIS was launched on the EOS Terra spacecraft on Saturday, December 18, 1999 at 18:57 GMT. MODIS Terra "First Light" was achieved when the MODIS Nadir Aperture Door opened on February 24, 2000. The Terra MODIS instrument began taking data using side-A electronics. For a complete look at the EOS-AM/ Terra mission, see http://terra.nasa.gov/.
